The HomePlug Powerline Alliance have cemented the “Green PHY” standard for energy-efficient powerline networking and energy management in stone,

Now the major German vehicle builders have defined a power connection standard to connect their electric or plug-in-hybrid vehicles to the mains power supply for charging. This includes using these HomePlug standards for transferring required data between the vehicle and the host power supply for charging-process control, metering and other similar applications.

The core benefit is to achieve a successful level playing field for connecting these vehicles to the “smart grid” for overnight and rapid charging. This also includes particular requirements like costing of energy used by “guest vehicles”, road-tax implications as well as grid integration such as off-peak charging or vehicle-to-grid setups for offsetting energy peaks.

This also facilitates IP linking to the Internet service via this connection thus allowing for some possibilities beyond the “obvious Internet applications”. One application I have often thought of in this context is the ability to integrate the vehicle’s infotainment system in to the home network.

Here, it could lead to synchronisation of maps, contact lists and media files between the home network and the vehicle or the ability to simply benefit from the data held on the vehicle’s infotainment system in the home network. This would be the networked equivalent of bringing a tape or CD that was in the vehicle’s glovebox or sound system in to your home so you can play it on your music system there.

At least there is an attempt to achieve a level playing field across the vehicle industry to support electric vehicles while catering for flexible setups.
